ZPL (Zebra Programming Language) is a page description language used by Zebra Technologies printers. It's a command language that allows users to define the layout and content of labels, receipts, and other printed materials. ZPL commands are sent to the printer as ASCII text, instructing it on how to format text, draw lines and boxes, print barcodes, and incorporate images. The language supports variable data, allowing for dynamic content to be printed based on input from external systems. ZPL is widely used in various industries, including retail, healthcare, manufacturing, and logistics, for applications such as product labeling, asset tracking, and inventory management. Different versions of ZPL exist (ZPL, ZPL II), with ZPL II being the more advanced and commonly used version. Understanding ZPL syntax is crucial for creating custom label designs and integrating Zebra printers into existing workflows. The language provides precise control over print output, enabling users to create highly customized and efficient printing solutions.
